Abstract

Widely adopted public key cryptography algorithms such as RSA and Elliptic Curve Cryptography (ECC) are susceptible to Shor’s algorithm, necessitating the development of quantum-secure cryptographic solutions. Quantum Key Distribution (QKD) has emerged as a potential approach for secure communication in the quantum era. However, existing QKD protocols suffer from inefficiencies in key exchange rates and vulnerabilities to attacks such as Photon Number Splitting (PNS) and Beam Splitter attacks. This paper proposes two dynamic QKD schemes that enhances security and efficiency by employing a dynamically changing control key. The unpredictability of these control keys ensures stronger randomness and resistance against adversarial attacks. The proposed scheme achieves a key exchange rate of 87.5%, significantly surpassing the 50% rate of the widely used BB84 protocol. These improvements demonstrate the potential of the proposed approach as a secure and efficient solution for quantum communication networks.
